Shellycoats are armor-clad pranksters from craggy coasts.

A shellycoat is a type of English and Scottish Merfolk that resides at the bottom of rivers and lakes. They wear a coat of seashells, which clicks and clacks when they walk on land. Some say they are dangerous, while others say they are simply mischievous. They enjoy playing pranks on nearby humans. They’ve been known to make drowning sounds as a prank. And when someone comes running to help, they disappear and laugh hysterically.
